Improvements in Resilient Wheels, of which.

the following is a specification, referenoe being had tothe accompanying drawings- This invention relates to resilient wheels:

of that type inwhicha hu'b section-and a rim section are cushioned withrespectto each: other by means of springs act ng as supports for the hub sectionwith respect l to the run sectiom andthe generalobject of my inven-= of this character having very few parts and in -w'hich not only is the-wheel cushioned from radial shocksbut the wheelis also cushioned against circumferential shocks. r

A :furtheriobject ofthe inventioniis to provide--a construction of this character wherein the hub section is adapted to move ;in; any direction; relative to the rim section,-

this movement however be ng resisted-by a" plurality of pairs of coilsprings embracing the hub section and supporting 1t. 1njre s1l1ent slings as they may be termed. i

Still another oh'ectof my invention is to provide meanswherehy the -tens on of the several springs may be'regulated H OtherOb ects will appear in the course in the accom panying drawings wherein;

Referring to these figures 1Q designates a.

hub section comprising an'inner rim 11 hav; ing outwardly projecting parallel flanges 12. This hub section is adapted to be secured to or formed as a part of the hub of the wheel and be either connected to or rotatable upon the axle skein in any suitable manner. Disposed normally in concentric relation to the inner rim 11 is a rim 13 having laterally disposed inwardly projecting flanges 14: and 14 which overlap the flanges 12. The rim 13 may carry any suitable tire, but I have shown the rim 13 as provided with a solid hard rubber tire 15. I do not Wish, however, to be limited to this as it is obvious that many diflerent forms of tire 1 is a side elevation of a wheel wheel;

Not only is the hub and run supported against radlal shocks, but

itli the construction described; the hiib is supported in extensible and contractible of each pair. Lateral stresses are resisted of course by the overlapping.engagement of the flanges 1-iandll With the flanges 12. The flange 14L is adapted to be removably connected to the rim and the opposite flange, as by means of bolts 20. By removing the flange l i access may be had to the interior of the Wheel, and the spring may be disconnected fromthe rim so that the hub may be taken out from its position Within the rim.

My Wheel constructed in accordance with the above description will effectively cushion a jar or shock communicated to the wheel, and wheels of this character may be used in place of Wheels for pneumatic or cushion tires of rubber such as. are now in use for automobiles. very cheaply made because ofits simplicity,
